Chemical name：Aldehyde resin A81

Introduction:

Aldehyde resin A81 is the condensation of urea and aliphatic aldehydes, colorlessly crystal or slightly yellowish, soluble in almost paint solvents except in water and widely compatible with coating raw materials. This range of products are specially developed for coatings or printing ink formulations

Usage and dosage:

Aldehyde resin A81 has been proved to be able to comprehensively and effectively improve coating system’s yellowing-resistance, adhesion, hardness, gloss, solid contents and fullness when being used as an advanced multifunctional additive. 3-8%

·The shallow color and good pigment wetting function enable Aldehyde resin A81 particularly suitable for producing all-purpose pigment preparations. 15-30%

·The low viscosity of its solution enables high-pigment-content pastes to be produced.

·The good heat-resistance character enables Aldehyde resin A81 to find its application in baking finish house to endow desired properties for coating film’s strength and hardness.

the application in advanced wood paint has proved Aldehyde resin A81 will significantly promote the natural grain and color of wood as well as strengthen the coating film’s elasticity, adhesion, hardness and toughness.
